Solid Walls – How to achieve 0.18 U-value

How to achieve a 0.18 U-value for solid walls

Are you going through building regulations for an upcoming project? You’ve likely been asked to achieve a 0.18 U-value for your walls if you are seeking acceptance from building control. Hitting this figure can be straightforward, however, can be much more difficult with cost and space restraints.

Understanding U-values

U-values measure the level of heat transfer through a structure. It is a sum of all the layer’s thermal R-values (thermal resistance) that makes up that part of the building. For example, a roof has a U-value, a window has a U-value, and so on.

Achieving a U-value is often crucial, as there is a minimum expectation to achieve building regulations.

The U-value target for 2024

The government has updated its Approved Document Part L about U-values, heat gain, and heat loss. The new target U-value came into play in June 2022. For more information on Part L follow the link on the UK government website – See Data Source.
